<p>Expression of VCAN in tissues and cells. <b>A,</b> VCAN protein expression from IHC compared with gene expression from RNAscope. Spearman rank correlation. <b>B,</b> Comparison of FAP<sup>+</sup> cells and percentage of α-SMA staining with number of VCAN<sup>+</sup> cells. Each dot is colored to represent TIP. Red = inflamed, Gray = excluded, Blue = desert. <b>C,</b> Structure of VCAN isoforms and the number of predicted CS chains attached. qRT-PCR for VCAN isoforms completed on RNA extracted from frozen TNBC tissues (<i>N</i> = 9; <b>D</b>), fibroblasts (<b>E</b>), primary fibroblasts from healthy patients (<i>N</i> = 2) and from paired tumor and surround areas of patients with TNBC (<i>N</i> = 4), immortalized mammary fibroblast cell line (HMF3S; <i>N</i> = 4; TNBC cell lines HCC38 and MDAMB468 (<i>N</i> = 4; <b>F</b>). Coculture of HMF3S with HCC38 and MDAMB468 at a 4:1 ratio (<i>N</i> = 4; <b>G</b>). CT values for each gene normalized to CT values for housekeeping gene RPS13 to form ΔCT. **, <i>P</i> < 0.01.</p>
